"voyager the vac keeps coming lose"

What is a "vac" and why do you think it's related to the fuel pump?

Any chance you could post a photo of that part? It sounds like you're describing a vacuum hose that is becoming detached. Normally that will cause the engine speed to increase but power will not. It can lead to stalling too.

I'll be out-of-town for a few hours and will check for your reply tonight. Don't want you to think I'm ignoring you.

Possibly. It all depends on what that hose is for. If it affects the MAP sensor which measures engine vacuum, that one has the biggest say in how much fuel enters the engine.
